Relatives of Renisha McBride have complained because authorities have not filed charges against the man, who has not been identified. They say McBride knocked on the man's door seeking help after her car broke down.

Prosecutors said they need more information from police before deciding whether to file charges. The 12-gauge shotgun is being analyzed by the state police crime lab, Seipenko said.

Mack Carpenter, one of the homeowner's attorneys, said on Friday that his client has cooperated and "has nothing to hide." He, too, declined to name the man.

"He was woken up between 3:30 a.m. and 4:30 a.m., and McBride never once said anything or cried for help," said Carpenter. "She just attempted to get into his house using the front door and also the side door and so that just scared the hell out of him."

Seipenko said that McBride was in a car accident and that hours passed between that time and her death.

Serwatowski told the Free Press that McBride was involved in a wreck several blocks from the house and left the accident scene. The wreck happened about 1:30 a.m. and the shooting at 3:40 a.m., the Free Press reported.

Friends and relatives held a rally Wednesday outside the house where the shooting occurred and had another rally elsewhere Thursday night. They allege that McBride was racially profiled by the white homeowner.

McBride's father, Walter Simmons, said he believes Wayne County Prosecutor Kym Worthy "will do the right thing and prosecute to the fullest extent. So we have confidence in that, and that Dearborn Heights police will cooperate and give all the information that's needed that's asked for."
